LS User Manual 7
1.1 SAFETY
CAUTION: Materials testing machines are very safe to use providing the instructions pre-
sented in this manual are followed precisely. We would like to draw your attention to both
the Electrical Safety (Section 2.0 page 7) and Operational Precautions, (Section 7.0 page
23). Please refer to both sections for details on safe operation of this equipment before
operating your materials testing machine.
Transparent splinter shields are available as an option to enclose the test sample if there is any dan-
ger of samples shattering as a result of the test. These shields have an electronic interlock such that
the test cannot be started until the hinged shield is closed. While not mandatory for many applica-
tions and countries, AMETEK Lloyd Instruments Ltd. strongly recommends that users consider tting
this option.
